Steady-state analysis of self-excited induction generator using scilab open-source software

Abstract

Self-excited induction generators (SEIG) are the most suitable machines for wind energy production at remote windy area due to many advantages over gird connected machines. Steady-state analysis is essential to predict their behaviors under actual operating conditions. In this paper, the implementation of SEIG steady-state simulation is described in a step-by-step approach. Scilab, free and open source software, is mainly used for computational environment to solve nonlinear algebraic equations describing behavior of the SEIG. The case studies are given to demonstrate usefulness of the developed approach through investigating the SEIG steady-state performances with various loading conditions. Using this approach assists in teaching, facilitates self-learning of both graduate and undergraduate students, and also helps in better analysis of induction generator during steady-state operation.
